Does the government need parliament’s approval to take military action?

Britain’s decision to take military action against Houthi forces in Yemen is one that is fraught with geopolitical, moral and legal arguments. Perhaps the most immediate is whether the government is required to seek prior parliamentary approval for such action. After all, the lives of British service personnel – and possibly, ultimately, of British civilians – are at stake.

Rishi Sunak called a cabinet meeting, and he also briefed the Labour leader, Keir Starmer; the shadow defence secretary, John Healey; and the House of Commons speaker, Lindsay Hoyle – but that was the limit of his consultations. (Presumably Sunak also briefed the King.) Other opposition figures were excluded from the process. The Liberal Democrats, Scottish National Party and Plaid Cymru are demanding that parliament – on recess until Monday – be recalled immediately, and Hoyle indicated he would assist with that. No 10, however, says there will be no retrospective vote on the airstrikes. The question of the role of the Commons in approving acts of war, therefore, remains live.
